Accuracy of denoised pyrosequences from the three multi-sample artificial community datasets retained by APDP and three alternative denoising approaches.

The number of false positives (FP) and false negatives (FN) is shown for near-match sequences are considered to be incorrect (TP only) or correct (TP+NM) sequences. In addition, the results are shown for each method after excluding denoised sequences with fewer reads than the minimum detection threshold of APDP (cutoff).
